Class extend upgrade from 1.1.1 to 2.3.0

[ndjb20]

Hi,

I am updating my code from 1.1.1 to 2.3.0, I've made all the changes required by the upgrade guide (and the comments). When I create a base class from a panel and then extend the base class I keep getting the loader error:
Uncaught Error: [Ext.Loader] Failed loading 'Base/Panel.js', please verify that the file exists

An example of the code I use is:
Ext.define('Base.Panel', {
extend: 'Ext.Panel',
(...)
});

Ext.define('Another.Panel', {
extend: 'Base.Panel',
(...)
});

Am I missing something, has someone else faced similar issues?

-- Edit --

Noticed this was happening because I had all the classes in a single file. I just want to upgrade easily. So my new question would be: Is there a way of leaving all the classes in a single file?

I have limited experience with Ext 2.x, but you might try posting this question in the Ext 2.x forum.

Oops, thanks, thought I had, must have put it in the wrong forum by mistake.

No worries. I've moved the thread over.
